How to set RSS_ENABLED to False without change the source code?

edit

This feature works like in the livesettings app, we use it internally, it's not the most straightforward, but possible.

LIVESETTINGS_OPTIONS = {
    1: { # site id
        'DB': True,
        'SETTINGS': {
            'SOCIAL_SHARING': { # this is name of the group of settings
                'RSS_ENABLED': True, # name of the setting
            },
        }
    }
}

You can change these via UI too: log in as admin and go to /settings url or click the "settings" link in the header.
